View Full Version : World Now More Urban Than Rural

Thought this was interesting. I would have thought this happened years ago.

Science Daily — There’s no big countdown billboard or sign in Times Square to denote it, but Wednesday, May 23, 2007, represents a major demographic shift, according to scientists from North Carolina State University and the University of Georgia: For the first time in human history, the earth’s population will be more urban than rural.

Working with United Nations estimates that predict the world will be 51.3 percent urban by 2010, the researchers projected the May 23, 2007, transition day based on the average daily rural and urban population increases from 2005 to 2010. On that day, a predicted global urban population of 3,303,992,253 will exceed that of 3,303,866,404 rural people.

Though the date is highly symbolic, the researchers – Dr. Ron Wimberley, Distinguished Professor of Sociology at NC State; Dr. Libby Morris, director of the Institute of Higher Education at the University of Georgia; and Dr. Gregory Fulkerson, a sociologist at NC State – advise avoiding the urge to interpret this demographic transition to mean that the urban population has greater importance than the rural.

Urban and rural populations, they say, rely heavily on each other.

Cities refine and process rural goods for urban and rural consumers. But if either cities or rural areas had to sustain themselves without the other, Wimberley says, few would bet on the cities.

“As long as cities exist, they will need rural resources – including the rural people and communities that help provide urban necessities,” he said. “Clean air, water, food, fiber, forest products and minerals all have their sources in rural areas. Cities cannot stand alone; rural natural resources can. Cities must depend on rural resources.”

In the United States, the tipping point from a majority rural to a majority urban population came early in the late 1910s, the researchers say. Today, 21 percent of our country is rural although some states – Maine, Mississippi, Vermont, and West Virginia – are still majority rural. In North Carolina, a rural majority held until the late 1980s.

Although rural natural and social resources are necessary for urban people and places, the researchers say rural people do not fare well relative to their urban counterparts. Maps of U.S. quality-of-life conditions show that poverty and low education attainment are concentrated in rural areas – especially the rural South – where the nation’s food, water and forest resources exist.

Over much of the globe, rural poverty is much worse than in the United States. Findings by the International Fund for Agricultural Development show that 1.2 billion of the world’s people live on less than what a dollar a day can buy. Globally, three-fourths of these poor people live in rural areas.

The researchers add that, in addition to having a highly disproportionate share of the world’s poverty, rural areas also get the urban garbage. In exchange for useable natural resources produced by rural people for urban dwellers, rural places receive the waste products – polluted air, contaminated water, and solid and hazardous wastes – discharged by those in cities.

Wimberley says that May 23, 2007, marks a “mayday” call for all concerned citizens of the world.

“So far, cities are getting whatever resource needs that can be had from rural areas,” he said. “But given global rural impoverishment, the rural-urban question for the future is not just what rural people and places can do for the world’s new urban majority. Rather, what can the urban majority do for poor rural people and the resources upon which cities depend for existence? The sustainable future of the new urban world may well depend upon the answer.”

I call BS. I'll give you polluted air (although I'll even debate that), but the rest of that is absolute crap. The majority of rural people here in the states have more concerns than this. I also don't know any one that has contaminated water due to pollution from cities. Solid and hazardous wastes, I can't think of a rural area near where I am where they have landfills that people live near.

The rest of the article is dead nuts on. I don't think that people realize that most of the world's people live in China, India, and Africa, all of which are pretty rural areas. Heck, given that, and the prevailing winds, etc., most of the rural people in these areas are not going to receive the air pollution from the cities in those areas. You could make the case in India, but China and Africa most of the winds are from rural areas to urban areas, not the other way around.

Depends on what you mean by contaminated but, the city of Milwaukee has done a pretty good number on Lake Michigan due to the sewer system dumping directly in the lake repeatedly.

Not sure how you're defining "pollution from cities", but it is very clearly established that waste water discharge from industrial plants is a major source of water pollution. I think many people associate the major industrial dischargers as "part of a city" regardless of where they are actually located. Thanks to industrial pretreatment practices in the US, this pollution is greatly reduced before it is released into public waters, but in areas like China where environmental regulation is in its infancy, things like industrial pretreatment don't exist (and therefore industrial plants discharge their waste directly back into the water), this is a *huge* source of pollution. See China, Yangtze.

My point is that most water systems are based upon wells, not surface water systems. Wells can be contaminated, but the gist of the article as I read it is that the urban areas are contaminating the water in the rural areas, and that just isn't true. Sure, you have some river pollution, I'm not going to dispute that, but look at where most of the populations are in these developing countries. They are on or near the coast. The rural areas are inland. The way the rivers flow, they are not contaminating the water that is being used by the rural areas.

Now, before someone comes out and says such and such in such and such has terrible water from pollution, I admit there are exceptions, but by and large most bad water from wells is naturally occurring and not caused by man.

When you get to river pollution, rivers have always been prone to disease causing bacteria and contamination due to rotting carcasses, animal feces, etc. That is why so many areas used well water rather than surface water for drinking. It was cleaner than the river water for the most part. With the advent of water purification plants, surface water became a great source for drinking water, but only in developed countries. Most of the rural areas worldwide do not have this luxury.
